Title: Process for the selective preparation of dib from an i-butene-containing c4 stream
Inventor: KRAMER HANS-JOACHIM
IPC: C07C11/02
Filed: 2001-08-20
Abstract: The invention relates to a process for preparing diisobutylene (DIB) from an i-butene-containing C4 raffinate I, in which the C4 stream is passed through a first hydroisomerization reactor (A) and a fractionation column (B) and is thus largely freed of 1-butene and 2-butene. It is subsequently dimerized over an acidic catalyst installed in a reactive column (E). The feed stream to this reactive column contains not only i-butene but also butanes which make the reaction temperature in the fixed bed controllable by removal of the heat of reaction. In the fractionation column (B), a side stream can be subjected to a further hydroisomerization in a reactor (C).

Title: Boot-strapped current switch
Inventor: GUTHRIE MARTIN G
IPC: G05F3/26
Filed: 2001-08-23
Abstract: A boot-strapped current switch is provided that includes a biasing network, a control signal, a transistor, a control switch and a boot-strapping circuit. The biasing network generates a substantially constant voltage on a biasing network output. The transistor has a control terminal, a first current-carrying terminal, and a second current-carrying terminal, wherein the first current-carrying terminal generates the output current of the current mirror, and the second current-carrying terminal is coupled to a first potential. The control switch is coupled between the biasing network output and the control terminal of the transistor, and is also coupled to the control signal. The control switch couples the first biasing network output to the control terminal of the transistor when the control signal is in a first state. The boot-strapping circuit is coupled between the control terminal of the transistor and a second potential, and is also coupled to the control signal. The first boot-strapping circuit injects the second potential onto the control terminal of the transistor when the control signal transitions from a second state to the first state in order to decrease the turn-on time of the transistor.

Patent CA-2358931-A1 (CA)
Title: Synchronization of ofdm signals
Inventor: YONGE LAWRENCE W
IPC: H04J11/00
Filed: 2000-01-20
Abstract: A method is described for temporally aligning a received symbol that is transmitted via orthogonal channels, e.g., OFDM channels, with a reference symbol and/or an earlier received symbol. The method includes computing phases (154) of the first symbol for the orthogonal transmission channels and comparing (157) the computed phases of the first symbol with phases of the reference. The phases of the first symbol are successively displaced by a predetermined phase shift which depends on the channel frequency to obtain a correlation result. The temporal alignment is determined by detecting a correlation maximum based on the correlation result and used to synchronize the first symbol with the reference. The reference can also be an earlier received symbol to provide autocorrelation. The received symbols can be processed by applying a window function, e.g. a Hamming, Hamming or Blackman window.

Patent CA-2371912-A1 (CA)
Inventor: MAGDASSI SHLOMO
IPC: A61K9/51
Filed: 2000-05-19
Abstract: La présente invention concerne des compositions et des procédés convenant pour l'administration in vivo d'agents pharmacologiquement actifs essentiellement insolubles dans l'eau (tels que le médicament anticancéreux paclitaxel) dans lesquels un agent actif au plan pharmacologique est administré sous forme de particules en suspension enrobées d'une protéine (laquelle agit comme agent stabilisateur). En particulier, la protéine et l'agent pharmacologiquement actif présents dans un support dispersant biocompatible sont soumis à un cisaillement élevé en l'absence de tout tensioactif classique et en l'absence de matériau noyau polymère pour les particules. Le procédé selon l'invention permet d'obtenir des particules d'un diamètre inférieur au micron. L'utilisation d'une composition spécifique dans des conditions de préparation précises (adjonction d'un solvant polaire à la phase organique), et le choix raisonné de la phase organique appropriée et de la fraction de phase permet la production reproductible de nanoparticules exceptionnellement petites d'un diamètre inférieure à 200 nm qui peuvent être stérilisées par filtration. Le système de particules obtenu dans le cadre de l'invention peut être transformé en une poudre sèche redispersible comprenant des nanoparticules d'un médicament enrobé d'une protéine, insoluble dans l'eau, et d'une protéine libre à laquelle des molécules de l'agent pharmacologique sont liées. On obtient ainsi un système d'administration unique en son genre dans lequel un agent actif au plan pharmacologique est facilement biodisponible (sous forme de molécules liées à la protéine), et où une partie de l'agent est présente dans les particules sans aucune matrice polymère.

Patent CA-2375606-A1 (CA)
Title: Spatially-encoded analyte detection
Inventor: KUHR WERNER G
IPC: C12Q1/68
Filed: 2000-07-17
Abstract: A flow-through microchannel (e.g. capillary) biosensor is described for the detection of multiple, different analytes (e.g. nucleic acids, proteins, sugars, etc.) targets in a sample by binding them to "complementary" binding partners (e.g. complementary nucleic acids, ligands, antibodies, etc.). The binding partners are immobilized in different sections of a microchannel (e.g.  a fused silica capillary). After fabrication of the biosensor, a sample is flushed through the capillary, and any target analyte(s) contained within the sample are bound to the immobilized binding partner(s) on the microchannel wall forming bound complexes. Finally, the bound complexes are simultaneously denatured along the entire length of the capillary and flushed out past a detector poised downstream, and the analyte concentration is measured (e.g., using sinusoidal voltammetry). Direct electrochemical detection of underivatized DNA is accomplished by oxidizing its sugar backbone and the amine containing nucleobase at the copper electrode. The elution time of the desorbed target DNA(s) is used for the sequence identification of the target.  Multiple genetic sequences can be diagnosed by using a single biosensor in this manner. The sensor is highly specific due to hybridization chemistry, and extremely sensitive due to electromechanical detection.
